Grapefruit warning: It's been long known that grapefruit does not mix well with many prescription medications. Now, scientists have expanded the list of medications that interact with grapefruit in potentially dangerous ways. On the revised list are 43 drugs, up from 17 in 2008. Widely-used cholesterol-lowering statins such as Zocor and Lipitor and blood-pressure medications such as Nifediac and Afeditab are among the drugs that might rise to harmful levels in the blood if a patient eats grapefruit or drinks grapefruit juice.

Today's talker: Some young women in Florida were offended by a recent survey on their sex lives -- and surprised that 12 pages of rather intimate questions came from the state health department, the Sun Sentinel reports. The survey, intended for women ages 18 to 24, asks women how many partners they've had, whether a partner has ever poked holes in a condom and how they feel about unprotected sex. Health officials say their intention was to gather information to improve family planning services. But they've cancelled a second mailing, after learning some of the first questionnaires were accidentally mailed to minors.
